Answer 1

Answer:

36,180

our area is is 36, 180

Answer 2

perimeter=160m

length=3 times of its breadth

so,length=20x3=60m

length=60m

area the rectangle=lxb

so,60x20=1200m

cost of fencing per metre =₹15

area of rectangle=1200m

cost of fencing for 1200m=1200x15=18000

so,cost of fencing for 1200m is ₹18000
